Dr. Dan G. Blazer-Iii

I am a colorectal surgeon and researcher who has been at Duke for about 25 years. I see patients who have issues with the small bowel, colon, rectum and anus. These issues include benign tumors, cancers, hemorrhoids and fistulas. The best part of my job is operating. The operating room is a special place, where we have been able to put a number of processes in place so things run smoothly and we can give patients the best chance at a good outcome. The fact that you can take a condition, operate and potentially cure a patient is fascinating to me. As a faculty member, I also enjoy when I have the chance to teach residents during the operation. When I am not at work, I enjoy fishing, hiking and playing tennis with my children. Dr. Mantyh is rated as a Distinguished provider by MediFind in Ureteroscopy.

Every day, my goal is to take the best surgical care of my patients' kidney or prostate cancer by offering the most up-to-date minimally invasive surgical treatments, while making sure that their experiences and outcomes at Duke Health are top-notch! As we look at the scans together and discuss biopsy results, it is important to me that I spend all of the time that my patients and their families need to clearly understand their diagnosis as well as all treatment options, so that we can make joint decisions about next steps and their treatment plan. Many of my patients are referred from all over the country to seek highly specialized urology care, including nonsurgical focal cryotherapy for prostate cancer, robotic surgery for prostate cancer, or robotic surgical removal of their kidney tumor called a partial nephrectomy, among other treatments, with our multidisciplinary, collaborative team. I always reassure and share my positive outlook with my patients as we navigate the health system together. My patients know that, as their physician, I will be their champion and advise them and guide them through their treatment. We are in this together.

As a colorectal surgeon, I specialize in the surgical management of a wide array of problems involving the small intestine, colon, rectum, and anus. My patients may be dealing with cancer or a variety of benign diseases including diverticulitis, inflammatory bowel disease or anorectal problems. I utilize minimally invasive techniques including robotics, laparoscopy, endoscopy, and transanal surgery. My primary focus is on ensuring that patients receive high quality, compassionate care while optimizing patient outcomes. My research interests include improving patient outcomes after colorectal surgery and quality improvement. Dr. Sherman is rated as an Advanced provider by MediFind in Ureteroscopy.
